- This video shows you how to build a fast pinewood derby car. It shows how to weight the car, prepare the wheels and axles, how to align and tweak the car.
For detailed pictures and information on this and other hobbies go to www.hobbyprojectsite.com.
I’m a retired dentist and grandfather who has been lured by my daughter and son-in-law to help my grandson build his pinewood car. Your video is by far the BEST I have seen!!! I do have a question concerning your lathe. I also have a mini metal lathe. WHAT kind of collets do you use to hold the wheels for truing OUTSIDE and INSIDE??????? Your video of the lathe spins too fast for me to see it. Thanx so much!!! Dr Bob
So, was the Scout holding the camera while his pinewood derby car was being built?
Thanks for uploading this video....very helpful! I like your techniques...a few good ones we'll use in our next race.
Silly dads everything he has shown you can be done by your son. Your teaching your son how to improve himself, true not everyone can be a winner but it's fun trying.
thanks of posting, lots of good tips! The video appears to show two different body types, is this right? or was there work (not shown) to reshape. I am wondering if there is any advantage with the one that has a triangular front versus the one that has more of a "T" shaped front for a rail rider style car. Thanks in advance for any information you can share.
At what point does the kid participate?
I'm with you on this. Just did our first pinewood derby and it was apparent there were purchased cars there. Not sure what you are teaching the kids at that point. ....
They can polish the axles, paint the car, sand the body, etc.
This is an info how to do guide for parent and child giving knowledge , and how to get the best out of the car while staying with the rules that are set by your group , The car now can be built by the child and the parent to a design the child draws and by working together , As for brought cars most likely does happen but then the parent and child miss out on the bonding building the car brings them those who buy pre built cars are cheating but mostly cheating themselves .
When they have a son!
What kind of collet are you using to hold the wheels in the lathe to true them?
I think that you are required to use the pre-cut slots for the axles.
+Aross7500 All depends on your rules.
It doesn't appear the axles are glued in. How do you ensure that they don't move/rotate after you have them adjusted?
WHAT DOES HE MEAN LEGAL
Michael Addison
Different groups have different rules. Boy Scouts of America (BSA) has some pretty stringent rules about what modifications are legal and what modifications aren't.
John A like what
Michael Addison
Like how far off the ground the car can be, how much it can weigh, what kinds of modifications you can make to the wheels and axles, what parts you can use, etc. For example you can't use wheels with bearings in them. You can't do anything more to the wheels than correct rough spots and defects. There's a laundry list of rules depending on how stringent your local race wants to get. Especially if the car will qualify for later races beyond the local level.
Typically, the axles will be snug enough to stay put, but some people will drill holes under the body of the car to add a few drops of super glue (or similar) to lock in the axle positions.
Bro what normal person has a metal lathe just laying around?
Why is it the left wheel should be touching and NOT the right? does it really matter which side touches?
You want the wheel that is /not/ raised to be touching. So if you raise the right wheel, your left wheel is the one the rides the rail, and vice versa. Just keep in mind that if you do the opposite direction, you want to tune the turning in the opposite direction as well.
too bad this violates our race rules like not using the pre cut axles, and raising one wheel!
how do you not melt the wheel?
wet sand the wheels with water. As you are sanding the plastic spritz with a misting water sprayer to keep plastic temperature lower.
Www.hobbyprojectsite.com doesn’t have anything. Is there a different site?
Pinewood are for boys to have fun not grownups trying to beat everybody
How much for the car???
TUNGSTEN GOOD CHOICE
I like using depleted uranium for weight as it is denser than tungsten. Whatever happened to kids just having fun?
Looked into this, and actually tungsten is denser than uranium. The reason the military uses depleted uranium instead of tungsten in penetrating rounds is that the government has a bunch of it and if they expend it overseas servicing targets, they no longer incur the storage cost here.
Why is it that parents always use their power tools to do this? That's cheating. Power tools should be banned for the Pinewood Derby. I feel like the only kid who ever makes their car. :P
Power tools mostly just make the job faster. All of this could be done with hand tools, save for perhaps the axle polishing, which needs something to spin them. Even a hand drill would suffice, and most people have access to those.
my son has enough sense that he can polish the wheels with a dremel or drill and apply the graphite. And I plan on letting him do this. Maybe his does too, maybe he is just showing you how he does it without his child, so you won't complain about how bad the child is doing on the video.
How on earth is that cheating? Pack meetings are a family event. The family should be involved. My son polished his axles, put in the weight, did all the woodwork, painted the car, drilled the holes. Even if I did that stuff, and he didn't, if you follow your race rules you are not cheating. Simple.
Videos like this is why kids choose not to build pinewood cars.
Yeah, cuz kids hate building awesome things and winning stuff. My girls do a derby with their girl scout troop and they loved watching these videos. I feel they learned more about the physics rather than putting on googly eyes and having no idea why cars win and don't win.
exactly..it takes the fun out of it for the children. it just becomes a competitive hobby for the parents.
Are you serious
This isn't rocket engineering, its a damn kids race for goodness sake. My 7 year old cared less at how fast it was , just as long as it looked cool.
